ESTIMATION

ODOMETRY

In general the localization of a robot in an environment is not easy, but for wheeled robot sometimes is possible to use the odometry. This techniques estimate the position of the robot from the wheels rotation.

EXTEROCEPTIVE

INFRARED

An Infrared sensor use a light to recognise an obstacle in front of the robot. In general you must evaluate the parametric curve to convert a tension value to distance. In this guide all information about the Sharp GP2D120.

ULTRASONIC

The SFR08 is an ultrasonic sensor with an internal micro controller to evaluate autonomously the distance of the obstacle in front of the sensor. In this guide all information about the ultrasonic sensors.
